In the first line of inquiry, students learned about the changing use of the buildings. They learned that sometimes buildings could change its functions. They also learned that the same building could be used for different functions. To explore the evidence, students walked around the school and its neighborhood to identify the buildings which have changed its functions. After going around the school, students and teacher discussed about the buildings that they saw. Some students could identify a house that was used as a restaurant. Some student could also identify a building which was used to be a bank but now it is used as a shop.
